“I use these IEM's at work and during travel, it's very easy to transport with the small metal case. It was difficult to achieve the good isolation, i tried 10+ pair of silicon cushions and i finally got one which fits perfectly into my ears. These are very sensitive IEM's, if you hate source noises stay away from them, i hear little hiss even with my desktop amp/dac combo Corda Aria, probably...” --Lewzke

Ultimate ears metro.fi range are often overlooked on these forums. There is a simple reason for this, they are not worth the price they quite often retail at. They are, however, frequently on special offers and very good deals, i've even seen them being given away with other things costing only about £50. Obviously when earphones are on special offer they should be compared to others in their...” --Marcus_C

For over 17 years we’ve been crafting the world’s finest custom in-ear monitors for discerning music listeners and industry pros. Traditionally, the “custom” in “custom in-ear monitors” refers to personally molded shells that fit you and only you. However, with the UE Personal Reference Monitors we’re taking customization to a whole new level.

These were my first IEMs, so obviously at first I thought that these were the pot of gold at the end of the rainbow. But after awhile...
Bass is clear and punchy. Highs are pretty clear but high mids can get a bit muddy IMO. I'll be honest, it takes a lot of work to get these to fit, and once you do, they are really uncomfortable, at least for me.

This is my very first pair of custom IEMs after trying almost all of the high end universal IEMs -- SE530, UE Super Fi 10, Etymotics etc. The sound of these UE11 Pros is superior in every way to all of the universal ones I had, but even more important they stay in my ear and provide a proper seal. Since my ear canals get very narrow, I found it very difficult to get any of my universals to...” --alyanm

“
Ok first of all I will be using my Sansa Clip as my source as I feel an iem should always be tested with portable sources. I paid $200AUD for them brand new, which is dirt-cheap by Australian standards. I do not believe in burn in, especially for armature drivers - owning and listening to many iems has shown me burn-in is just a mental phenomenon where the brain adjusts to a new sound...” --ProjectDenz

“I wonder why UERM is often disregarded when picking from $1000 range. I'm guessing that it's due to "only" having 3 drivers, versus having 8 drivers per side. I can say with confidence that driver number does not equal sound quality(for the most part). Another reason I see why UERM might not be picked is its sound sig. It's perfectly flat. Personally, I love this. Reference sound with...” --kimvictor

I had owned the UE-10's before this for about 3 years. So upgrading to these was a huge improvement in my opinion. Very nice full sound, with improved frequency response from 20 Hz to 18,000 Hz. Bass is much more present on these but not too overly stated. Gorgeous build quality. Very happy with these In ear monitors, I also own the JH-16's and still love listening to these all the time on...” --Richard Devine
